Carbon and nitrogen loss rates during aging of lake sediment: Changes over 27 years studied in varved lake sediment
We used a collection of ten freeze cores of annually laminated (varved) lake sediment from Nylandssjön in northern Sweden collected from 1979 to 2007 to follow the long‐term loss of carbon (C) and nitrogen (N) due to processes that occur in the lake bottom as sediment ages. We compared specific year...
